This is normally caused by Stephan's patches. His patches were
originally against 6.3, and he ported them to 6.4, but he normally does
lots of development without any communication with us, sends us a huge
patch, and we normally have to clean up the edges somewhat. This patch
actually caused fewer problems than the HAVING patch he submitted.

In fact, I didn't even know he was working anymore, and then I recieve
this huge patch, with a huge thesis that Thomas is merging into the
docs. He is in the Army now, and probably unreachable.

Basically, I think our hands are tied on this one. Not really sure we
could have done anything different. The patch is usually beefy enough
that is worth our effort to polish it. To his credit, he did more
regression testing this time, so we have fewer problems. All his stuff
has /***S*I***/ next to it, which I will remove once we resolve issues
with his patch.

Same cause.
